PATENT oFFlcn DRAINING DEVICE.

Application filed Apri1`22,

To @ZZ 'whom t may concern.'

Be it known that l, Enwnnn C. DANIEL- soN, a citizen of the United States, residing at Sturgeon Lahe, in the ccuntyofldine and State oit lf/linnesota, haveinvented certain new and useful Improvements in Draining Devices; and I do hereby declare the fol-i lowing to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art `to which it appertains to make anduse the same. y

This invention relates to draining devices, and more particularly to a device adapted `for use in connection'with well pumps.

One of the main objects ot the invention is to provide a device of the character stated ot simple construction and operation which l may be readily app-lied't-o a pump otl standard construction and may be 4easily oper ated from the pump platform for draining water from the water pipe or standard so as to prevent freezing of the pump. A fur ther object is to provide lsimple and eiiicient means which may be produced at relatively small cost and maybe readilyapplied without necessitating changes in the pump structure. Further objects will appear from the4 detailed description.

In the drawings:

Figure 1 is a side view of a pump of conventional construction and the pipe or standard associated therewith showing a device constructed in accordance with my invention applied. y

Fig. 2 is a central vertical section through the device and the contiguous portion of the pump standard. A l

Fig. is a top plan view of the device.

The draining device designated generally by 1 is formed'of two sections 2 and 3`which are adapted to be secured tightlyabout pipe standard 4 depending from pump 5 of any suitable type.

Section 3 is provided with a cylindrical bore 6 extending from the upper end thereof, the lower portion of this bore being reduced and of inverted conical shape. as at 7, to snugly receive a correspondingly shaped valve 8 having a reduced Sternv 9 extending` through bore 6 ax'iallv thereof,

. the upper end of this stem proiectinq above the upper end of member 3. The valve is normally held in depressed or seated posit tion by an expansion coil spring 10 mounted about valve stem 9, this spring being confined between a metallic washer 11 resting` freezing of this water Specification of Letters Patent.

upon a leather washer 12 seated upon the upper end of Vvalve 8, and a washer 13 secured in the upper end of bore 6. The up per end portion `of valve stem 9 is reduced, as at 9, to form a shoulder 9b adapted t0 engage washer 13'for upward movement of the valve so as to prevent injury to spring .10. The leather washer 12 is adapted to fit snugly the inte rior of bore 6 so as to prevent leakage of water into the upper portion oi' the bore and consequent corrosion oli-the spring.

Member 3 is provided with a water re ceivingA duct 14 lcommunicating with the lower reduced portion 7 of bore 6 a short distance `above the lower end thereof, this duct being in register with a drainage opening 15 provided through the pipe standard 4. Member 3 is further provided with a water discharge duct 16 extending from the lower end thereotl and communicating with the lower end of the reduced portion 7 of bore 6. A11-operating rod 17 is secured to the upper end of valve stem 9 and eX- tends through pump platform 18, this rod providing means whereby the valve may he readily raised so as to permit water to drain out of pipe 417A suitable cover plate 19 is preferably, though not necessarily, provided for the drainage device 1, this cover plate acting to eifectually prevent spreading apart of the upper ends of members 2 and 3 while also providing a guide for reciprocation of valve stem 9.

In practice, the drainage device will be placed lfrom ten to twenty feet below the pump platform, depending upon the depth of the well and the length of the pipe standard 4. Normally the valve 8 will be held in depressed or seated position so that the water column in pipe 4 will be maintained thus avoiding allnecessity for priming the mump. In cold weather when there is danger ot the water in the pipe freezing, the valve mav be raised so as to permit the water to readily drain from the pipe standard from above the cylinder thus eliminating In this case. also, the draining1 ot the water from the standard will not necessitate priming of the pump such as is necessary where the water is drained from the pump cylinder. as is a common practice.` As will be appreciated,

this device mav be readily applied to a pump pipe standard without necessitating any changes in the construction of the positively limiting standard and it is, therefore, very practical and eiicient.- Also, While the device has been yillustrated and described as used in connection with a pipe standard for a pump,

it Will be understood that it may be equally well applied to any pipe in which a. water column is formed, such as a pipe for supplying water to a storage tank, or for simi- Y lar purposes.

While I -have illustrated and described the preferred rform of my invention it will be evident that, in practice, it may be desirable to resort to slight changes in the construction and arrangement of the details of the invention, and I inte-n d to include all 'suchvariations,k as fall within the scope of the appended claim, in this application in which a preferred form only of my inven- 'be applied ,to the sides of the standard.y 25Y means for clamping the sections in position upon the standard, one of the sections being, provided with a longitudinally disposed Y bore and a longitudinally disposed counterbore, the bore and counter-bore being` in alinement with each other, the said section being' further provided with an openingll Which is adapted to communicate with the opening` in the standard and which coniinunicates at its inner end with the counter-bore in the section, a plate applied to the last mentioned section` and closingthe upper end of the counter-bore and secured to the other section` a valve lslidably mounted in the counter-bore and itting' snugly therein and adapted to niove across the opening which lead into the counter-bore and adapted close against the end of the bore, and a spring located in the counterbore and bearing;- at one end against the fixed abutment and at its other end against the said valve and beingr under tension with a tendency to normally hold the valve in position across the opening' which commanicates with the counter-bore.

In testimony whereof' I aliix my signature f in presence of two witnesses.
